I have a 10-7501 Emergen manual transfer switch for my generator. I
want to hook my hot water tank to this panel for use when the power is
out during our hurricane season. Here's what I have - the hot water
tank says 4500 watts on the upper and 4500 watts on the lower for a
total of 4500 watts. Wired at 240v - if I did my math right, that
should be about 18.75 amps. Currently it is on a 25 amp breaker on my
main panel. The Emergen switch has 20 amp breakers. So if I use the
switch bar to combine two 20 amp breakers to pick up both wires, one on
each breaker, on the Emergen panel, I should be ok, right? My generator
is rated at 5250w, so I know that all other breakers on my Emergen
switch need to be off while the hot water tank is on, but I only plan
on running the hot water tank maybe for an hour every other day. Thanks
much fo your responses.
